Series leader Scott Riggs passed pole-sitter Jack Sprague with nine laps left and went on to win late Saturday's NASCAR Craftsman Truck race at Sparta, Ky.
Sprague, who led much of the race, passed Riggs to gain the lead on Lap 140, but dropped behind on the next lap when his truck developed engine problems. He finished third.
Riggs extended his points lead over second-place finisher Joe Ruttman from 49 to 59.
Sprague and Ted Musgrave traded the lead several times during the first 100 laps. Musgrave took the lead on Lap 118 only to be bumped into the wall while trying to pass Matt Crafton on the outside.
